As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including the computer cover, filler brackets, front-panel inserts, and so on) removed or opened.
Your computer is equipped with one of the following:
A fixed-voltage power supply — Computers with a fixed-voltage power supply do not have a voltage selection switch on the back panel and operate at only one voltage (see the regulatory label on the outside of the computer for its operating voltage).
An auto-sensing voltage circuit — Computers with an auto-sensing voltage circuit do not have a voltage selection switch on the back panel and automatically detect the correct operating voltage.
A manual voltage selection switch — Computers with a voltage selection switch on the back panel must be manually set to operate at the correct operating voltage.
To help avoid damaging a computer with a manual voltage selection switch, be sure that the voltage selection switch is set to match the AC power available at your location:
115 V/60 Hz in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
NOTE: The voltage selection switch must be set to the 115V position
even though the AC supply in Japan is 100 V.
230 V/50 Hz in some regions in the Caribbean and South America and most of Europe, the Middle East, and the Far East
NOTE: Fixed-voltage power supplies and auto-select power supplies do
not require a voltage selection switch. Your power supply may not have
this switch. Check the regulatory label on the outside of the computer for
your power supply type.
Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
To avoid shorting out your computer when disconnecting a network cable, first unplug the cable from the network adapter on the back of your computer, and then from the network jack. When reconnecting a network cable to your computer, first plug the cable into the network jack, and then into the network adapter.
To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting or connecting a non-USB device from the computer.
To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a three-wire cable with properly grounded plugs.
To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply.
Be sure that nothing rests on your computer's cables and that the cables are not located where they can be stepped on or tripped over.
Do not spill food or liquids on your computer. If the computer gets wet, contact Dell. See "Contacting Dell" in the Owner's Manual for instructions on obtaining technical assistance.
Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.
Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do not place your computer in a closed-in wall unit or on a bed, sofa, or rug.
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION: Do not attempt to service the computer yourself, except as explained in this guide and elsewhere in Dell documentation. Always follow installation and service instructions closely.
Ground yourself by touching an unpainted metal surface at the back of
the computer before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer to dissipate any static electricity that might harm internal components.
Disconnect any devices connected to the computer, including the
monitor, from their electrical outlets to reduce the potential for
personal injury or shock. Also, disconnect any telephone or
telecommunication lines from the computer.
Disconnect the power cable to your computer, and then press the
power button to ground the system board.
In addition, take note of these safety guidelines when appropriate:
When you disconnect a cable, pull on its connector, not on the cable itself. As you pull connectors apart, keep them evenly aligned to avoid bending any pins. Also, before you connect a cable, make sure that both connectors are correctly oriented and aligned.
Handle components and cards with care. Don't touch the components on a card. Hold a card by its edges or by its metal bracket.
CAUTION: There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
To prevent static damage, discharge static electricity from your body before you touch anything inside your computer and periodically while you work inside the computer. You can do so by touching an unpainted metal surface on the back of the computer.
You can also take the following steps to prevent static damage:
Do not remove items from their antistatic packing material until you are ready to install them in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
When transporting a sensitive component, first place it in an antistatic container or packaging.
Your computer uses a lithium battery. For instructions about replacing the lithium battery in your computer, see "Replacing the Battery." The lithium battery is a long-life battery, and it is very possible that you will never need to replace it.
Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
The computer can be used in either a vertical or horizontal position.
To use the computer in a vertical position, you must attach the computer stand:
